as shown in Figure 8-23. Remove and save this hardware for later. Lift the left side
panel approximately 3 inches up to clear the structures holding it in place and pull
straight away from the filtered hood until free of the filtered hood. Store away from the
filtered hood and keep track of this panel.
Step 3
Once exposed, locate the hardware holding the
sensor in place. First, unplug the sensor from
the power supply cable and let the cable hang. If
possible, use a second person to hold the white
capped head of each screw from inside the
filtered hood and remove the four nuts with a nut
driver. Remove the sensor from the screw studs.
Save all hardware.
Step 4
Reverse step 3. Place the new sensor on the
studs identified in Figure 8-24. Using the nut
driver, secure the four nuts holding the sensor in
place. Hold the capped screw heads from inside the filtered hood if needed. Once the
new sensor is firmly in place, plug the cable from the power supply into the sensor port.
Step 5
Power up the filtered hood. If in alarm, check eGuard for the explanation. If eGuard says
the sensor has been replaced, press the
[mute] button on the command module. If the
alarm is anything other than a replaced message, disconnect the power, re-check all
electrical connections and try again.
When properly working, reinstall the side panel back on the filtered hood, and reapply
the screw removed.
Step 6
Recalibrate the anemometer by the following the steps in Section 4: Calibrating the
airflow sensor . Once this is complete, the filtered hood should be working properly.
